Abstract: A hinge for notebook computers is disclosed which includes a cam mechanism to keep the lid closed when the computer is not in use and a cooperatively operating friction mechanism to maintain the lid's position when in use. The friction mechanism operates in conjunction with the cam mechanism to enhance the operational characteristics thereof. Previous attempts at cam hinges for laptops demanded that the cam mechanism, which provides torque in opposition to the frictional torque as the lid nears the closed position, be capable of overwhelming the friction mechanism in order to perform its intended function. This placed a strain on the cam mechanism, resulting in the need for a stronger heavier hinge, and stronger heavier attachment points in the laptop. By controlling the magnitude of the friction by substantially reducing it at the moment of cam engagement, the cam hinge becomes a far more practical device.
